Table A-9- Tennessee Fuel Combustion Emission Regulations
Particulate Matter
A. Choice of Standards - Existing Fuel Burning Equipment
The owner or operator of existing fuel burning equipment may
elect to be regulated by emission limits established by either
Subsection 1 or 2 of this section unless otherwise indicated.
After July 1, 1975, all existing fuel burning installations
shall be required to comply with the emission regulations as
given in Subsection 2. The owner or operator of a facility
in existence on or before the effective date of this regulation
must designate, in writing, to the Technical Secretary, not
later than July 1, 1972, which Subsection is selected. In the
event the owner or operator makes no selection within the pre-
scribed time period, Subsection 2 will be applicable.
1. Diffusion Equation
For existing installations up to and including 4000 million
Btu per hour total plant heat input, the maximum allowable
particulate emission shall be as determined by the following
equation, provided, however, that no emission in excess of
six tenths (0.6) pounds per million Btu shall be permitted
from any installation. Such limit shall be achieved by
August 9, 1973.
n - 20650 a h
Q0.75
in which D is the maximum allowable particulate emission
in pounds per million Btu heat input, h is the stack height
in feet, a is a diminsionless factor of 0.67 for stacks
of 200 feet height and less, and 0.80 for stacks in excess
of 200 feet, and Q is the combined heat input in Btu per hour
to the entire fuel burning installation.
-------
Table A-9. Tennessee Fuel Combustion Emission Regulations (Contld)
When more than one stack of the same height serves a given
installation, the allowable emission limit as determined
by the above equation shall be further reduced by dividing
the emission limit so obtained by nO-25} where n is the
number of stacks of equal height. Stacks varying in height
may be construed as being of equal height provided a weighted
average stack height is used in computing the allowable
emission limit.'
2. Heat Input
The maximum allowable particulate emission limits as given
in this Subsection are based upon the total plant rate of
input to one or more stacks.
For existing installations up to and including 4000 million
Btu per hour total plant heat input, the maximum allowable
particulate emission shall be determined from Figure A-l,
existing curve, shall be achieved by August 9, 1973.
Emission limits for all existing fuel burning installations
in excess of 4000 million Btu per hour will be determined
by Figure 2-2, existing particulate curve, up to 10,000 million
Btu per hour heat input. Emission limits from existing
installations in excess of 10,000 million Btu per hour will
be determined from Figure A-l. This allowable emission
standard must be attained on or before July 1, 1975.
B. New Fuel Burning Equipment
For fuel burning installations constructed after the effective
date of this'regulation, the maximum allowable particulate emission
shall be determined from Figure A-l, new particulate curve, based
upon the total plant rate of heat input to one or more stacks.
This allowable emission standard must be attained at the time such
fuel burning installation begins operation.
Sulfur Dioxide
A. On or after July 1, 1975, the owner or operator of an air contaminant
source located in a Class I County shall not cause, soffer, allow
or permit the emission from that source of sulfur oxides (calculated
as sulfur dioxide) in excess of 1.6 pounds per million Btu heat
input, maximum 2 hour average.
B. On or after July 1, 1975, the owner or operator of an air contaminant
source located in a Class II County shall not cause, suffer, allow
or permit the emission from that source of sulfur oxides (calculated
-------
Table A-9. Tennessee Fuel Combustion Emission Regulations (Cont'd)
as sulfur dioxide) in excess of 3.0 pounds per million Btu
heat input maximum 2 hour average.
C. On or after July 1, 1975, the owner or operator of an air contaminant
source located in a Class II I County shall not cause, suffer, allow
or permit the emission from that source of sulfur oxides (calculated
as sulfur dioxide) in excess of 4.0 pounds per million Btu heat
input, maximum 2 hour average.
D. After January 1, 1973, fuel burning installations with a rated
capacity of 250 million Btu per hour or less heat input, constructed
after April 3, 1972, shall not cause, suffer, allow or permit the
emission of sulfur oxides (calculated as sulfur dioxide) in excess
of those limits specified in A), B) and C) above.
E. After January 1, 1973, the owner or operator of an air contaminant
source with more than 250 million Btu per hour heat input, constructed
after April 3, 1972, shall not cause, suffer, allow or permit the
emission from that source of sulfur oxides (calculated as sulfur
dioxide) in excess of the following:
a. 0.08 Ibs per million Btu heat input, maximum 2 hour average,
when liquid fossil is burned.
b. 1.2 Ibs per million Btu heat input, maximum 2 hour average,
when solid fossil fuel is burned.
c. Where different fossil fuels are burned simultaneously in
any combination, the applicable standard shall be determined
by proration. Compliance shall be determined by using the
following formula:
Y(0.80)
X + Y + Z
where: X = % of total heat input derived from gaseous
fossil fuel
Y = % of total heat input derived from liquid
fossil fuel
Z = % of total heat input derived from solid

D. After January 1, 1973, fuel burning installations with a rated

after April 3, 1972, shall not. cause, suffer, allow or permit the
emission of sulfur oxides (calculated as sulfur dioxide) in excess

E. After January 1, 1973, the owner or operator of an air contaminant

b. 1.2 Ibs per million Btu heat input, maximum 2 hour average,

c. Where different fossil fuels are burned simultaneously in

following formula:
